Extended Import/Export

Added support for importing and exporting to/from:

• SAS Data Files (binary)
• SAS Transport Files
• SPSS Data Files (binary)
• SPSS Portable Files (Replaces V6 SPSS POR import functionality)
• Minitab Data Files (binary)
• JMP Data Files (binary)
• Enhanced speed for the Unstack operation for sparse data situations.
• Oracle-write back can be performing using optimized native Oracle operations providing improved speed for scoring/writeback operations on a large IDP datamining source.

• Support for maintaining integrated "data-graphs" exploratory environments.
• STATISTICA Graphs will update when the source Spreadsheet data change even after the respective STATISTICA analyses are closed.
• Graphs can be re-linked to new Spreadsheets and Variables, allowing currently customized graphs (titles, scaling, embedded objects, bar shading, etc.) to be used as "Templates" for deployment to different data sets.

• Tight integration between Graphs and their source Spreadsheets.
• Brush points on Scatterplots and the Cases will automatically become marked in the respective Spreadsheet, so the subsets can be used in subsequent analyses.
• Brushing states will propagate to the source Spreadsheet and then to all other open Graphs based on the same Spreadsheet; this feature enables the user to brush points on one graph and view the corresponding Cases highlighted on other open Graphs.
• Brushing events will update the Spreadsheet marking Cases as Labeled/Unlabeled, Excluded/Included, Marked/Unmarked. Related graphs tied to the same data can then be updated to reflect the brushing events performed on the first graph.
• Histograms can now be brushed; if selecting from the Spreadsheet, then the bars will be partially filled to represent the portion of the histogram that is selected by the cases; if selected from the histogram, then all component cases are selected.
• "Raw Data" display for Brushing of Box & Whisker plots. When selected this option includes the raw data points in the display.
• Box and Whiskers plots can now have Jitter. Jitter will offset the points slightly so you can distinguish among points. This makes it easier to get tooltip information about certain points, and to select points for brushing.
• Box Plots can now be brushed. If raw data points are displayed then the individual points are selected in the Spreadsheet. If raw data is not displayed then selecting the box will select all points associated with it.
• Text string can be used as a graph marker point.

• All STATISTICA Analyses and Graphs now support the selection of one or more "By Variables." The specified analysis is repeated for each unique level (value) of the "By Variables." For example, a Multiple Linear Regression model can be specified and calculated independently for subsets of cases defined by each unique value of variable City (e.g., Dallas, Atlanta, Pittsburgh, Chicago...).

Case Metadata:

• Marker Type: Defines the point marker shape to be used for the respective Case(s); used in Graph Types such as Scatterplots (for example, one particular case can be assigned a "red star" marker, and it will appear as such in all scatterplots).
• Marker Color: Defines the point marker color to be used for the respective Case(s).
• Excluded: User can mark a case as Excluded. An Excluded case will be omitted from calculations, but will still be present in graphical displays.
• Hidden: User can turn off a point in graph, i.e., the point will still be used in computations, but will not be displayed in a graph.
• Label: User can select to label individual cases within graphs.

Variable Metadata:

• Measurement Type (Auto, Continuous, Categorical, Ordinal): Used for automatic variable classification in Analyses and, optionally, automatically populating variable selection list boxes only with variables of the appropriate types.
• Excluded: Prevents display in Variable selection dialogs.
• Label: The User can define a variable as a Label variable. The values of a Label variable will be used as point labels within appropriate graphs.
• Case state: User can save case states to a specified variable.
• Properties: User can create custom metadata fields (name-value pairs) to be stored and associated with a Variable. For example, a User can define an "Upper Control Limit" property for a variable assigned a value of "2.6". A STATISTICA Visual Basic (SVB) macro can query the Variable Properties, including the custom Upper Control Limit Property, to apply it to Quality Control Charts based on this Variable. With this approach, the same SVB macro can be applied to different data and dynamically use appropriate QC Chart limits and specifications.

• New default behavior in Workbooks is to display the contents of a folder, when the folder is selected, as a pane of the respective Spreadsheets and Graphs from that folder displayed in form of a grid of items (adjacent to each other).
• Workbooks now support the ability to View/Print the contents of a Workbook folder in a user-defined grid configuration.
• V7 Workbooks can now be saved in Version 6 format; each item in the workbook will be exported to V6 format.
• The Workbook multi-item display supports selecting and copying selected items from the display using the standard Shift-click or Control-click conventions.

• Currently specified case selection conditions can now be automatically displayed in title areas of all respective graphs (generated from the case selected subsets) and in the header areas of all result spreadsheets.

• Export all document types into (editable) PDF format.

• Support for Integrated Internet Explorer (IE) Windows in the STATISTICA Application.
• The integrated IE Window offers one more method supported in STATISTICA to easily build custom User Interfaces, in this case, using the standard HTML scripting.
• IE Windows supports HTML applications that can include native STATISTICA Spreadsheet and Graph objects for interactive editing, brushing, etc.
• IE Windows support hosting of native STATISTICA Spreadsheet and Graph objects for interactive editing, brushing, etc.
• Seamless integration of desktop STATISTICA and WebSTATISTICA running on a remote server.

• The import of text files has been enhanced through the "auto" text import method. Users can now have the system automatically determine which columns should be imported as variables of type Text (instead of variables of type Double with text labels), or users can manually specify which columns are to be imported as text.

• To speed up and simplify the process of selecting variables for analyses, Variable selection in Analyses and Graphs will (optionally) limit the display of Variables to the types that are appropriate for their respective roles in the Analyses. For example, in "By Group" Analyses, by default only Categorical Variables will be displayed for selection as the By Variables.

• STATISTICA Concurrent Licensing has been enhanced to allow for more granular licensing of modules and offline usage while a STATISTICA User is disconnected from the network (as well as supporting "trial period" usage of individual modules).

• Improved user interface to define complex sorting scenarios with very many keys.
• Support via automation for up to 14 sort keys.

• Merging from both open and disk-based Spreadsheets.
• Addition of "Cartesian-join" merge.
• Enhanced user interface.

• Added ability to Interleave output when stacking.
• Stacking - Unstacked variables can be included/excluded from results.
• Unstacking - Added options for handling multiple cross tab values.

• RE_SEARCH - search for text in a variable using regular expressions.
• RE_MATCH - compare text using regular expressions.
• RE_REPLACE - text replacement in a variable using regular expressions.
• LIKE - compare text using an operator similar to SQL's LIKE keyword.

• Go even further using STATISTICA as an efficient programming platform for developing highly interactive custom graphics applications.
• Embed a wide variety of ActiveX controls within STATISTICA graphs.
• The Object Model help file, stv6om.chm, has been reorganized to make the structure easier to understand. Documentation has been added for the SEWSS object model.

• A new method of categorization in graphs allows for up to 255 distinct categories of integer or non-integer values.

• Enhanced breakdown tables generated with elimination of empty rows in generated tables.

• STATISTICA QC Charts support aggregated data (means, ranges, standard deviations) as input. This capability is particularly useful when automated data collection equipment and instruments output only aggregated data for each sample.

• Gage Linearity analysis.
• 5,000 cases limit has been removed.

Aggregated Data
SEWSS supports aggregated data (means, ranges, standard deviation) as input. This capability is important and useful when automated data collection equipment and instruments output only aggregated data for each sample.

21 CFR Part 11 Compliance
There are extensions to SEWSS offer options to better keep track of SEWSS users' activities and to increase administrator's control over the way in which SEWSS is being used. These features are also required for complete compliance in a 21 CFR Part 11 environment. This includes logging of system changes, implementing a Windows integrated logon environment, and locking Spreadsheets and Graphs from modifications.

• Integrated NT authentication allows administrators to import users from any NT domain and define as part of the SEWSS domain. Once a SEWSS domain user is defined no further log-on prompt is required to log-in to SEWSS.
• The Jet4.0 OLEDB provider can now be used when connecting into an external data source offering enhanced options for accessing certain databases.

STATISTICA NIPALS Algorithm (PCA/PLS) - an implementation of a number of techniques known as Principal Component Analysis (PCA) and Partial Least Squares (PLS). In STATISTICA, PCA and PLS are implemented using the state of the art NIPALS algorithm (Nonlinear Iterative Partial Least Squares) a mathematical procedure designed to extract systematic variations, relationships, and information in datasets. STATISTICA NIPALS simplifies the analysis at hand while effectively combating the curse of high dimensionality (typically present when the number of variables is large). STATISTICA NIPALS is also particularly suited for use in data diagnostics, making it an ideal tool for use in Quality Control in many areas of science and technology. A few examples are pharmaceuticals, biochemicals and semiconductor industry. Important features include:

• Scalability: The ability to handle datasets with very large number of variables.
• Data diagnostics and inter-variable relations: Capable of applying PCA to data diagnostics, while also using Partial Least Squares for relating a number of predictors to a set of outcome variables (whether in a classification or a regression problem).
• Integrated Graphical Analysis: Wide selection of integrated graphical techniques including batches plotted in the component space, importance plot of components, and univariate and multivariate QC Charts.
• Cross-validation. Integrated options for cross-validation to evaluate the number of components to extract.
• Quality Control. Wide selection of univariate and multivariate QC Charts for offline analysis or automatically-updated as new data are collected.
